Their Finest, based on Lissa Evans's novel Their Finest Hour And A Half, is a witty, romantic and moving portrayal of a young woman finding her way, and her voice, in the mayhem of war... and the movies.
1940, London, the Blitz; with the country's morale at stake, Catrin, an untried screenwriter, and a makeshift cast and crew, work under fire to make a film to lift the nation's flagging spirits; and inspire America to join the war. Partnered with fellow writer, Buckley, the pair, along with fading matinee idol Ambrose Hilliard, reluctantly joins forces on a movie to warm the hearts of the nation and capture the imagination of the US public.
Other characters include Ambrose's agent Sammy; Sammy's sister Sophie; Ellis, Catrin's war artist husband; and Phyl Moore, the woman tasked with keeping the production on track.
